I had some large values before this got merged and due to this
slowing down builds 2x I reduced the defaults. The current defaults
are no known as TEST_KALLSYMS_LARGE.

I tried to clarify the ranges known we can use to mess with this test
a bit more in the recent fixes on modules-next [0] so since you want
to see some things blow up try TEST_KALLSYMS_MAX, on some systems this
is reported to crash the build.

It is why I had reduced the original values a bit...
